Pker>>I got it frm MAHA through a fren in US. Eastgear are selling them. I think u should get extra Li Batt instead of running the route of external batt packs. Frm what i know, the G2/3 have a very long batt life =)
G3 don't need lah. You'll be adding additional weight for little gain in battery life. D7series is another matter though as the battery life is really pathetic.
pardon me ...as from what i see here the problem is technical and technique.....please post to the appropriate forum.....such as the technical discussion ...
